This application claims priority to Indian Patent Application No. 202141039988, entitled “ABRASIVE SCRUBBER,” by Sumi DINKAR et al., filed Sep. 3, 2021, which is assigned to the current assigned hereof and incorporated herein by reference in its entirety.

FIELD OF THE DISCLOSURE

This disclosure relates, in general, to articles and methods regarding scrubbing articles with antimicrobial properties and improved performance. The abrasive articles comprise a first fiber element comprising a woven or non-woven material; and a second fiber element comprising metal, wherein the second fiber element comprises at least one interlocking arrangement. The scrubbing articles possess physical and performance properties that beneficially exceed the state of the art.

BACKGROUND

Scrubbing articles are used in various applications to condition and clean the surface of a workpiece to a desired condition. Various types of scrubbing articles are used for cleaning a variety of workpieces, such as cooking and eating utensils and the like by abrasively removing food particles, sticky oily residues, and associated unhygienic contaminants to restore the workpieces to good and acceptable conditions before every use.

Scrubbing articles have been made from a variety of materials, however such scrubbers suffer various disadvantages, such as disintegrating relatively quickly, are difficult to keep clean, can scratch work piece surfaces, are not able to quickly remove stubborn food deposits, and are unpleasant to the touch.

There continues to be a need for improved abrasive products, including improved scrubbing products.

Examples

Samples S1-S4 were prepared according to the following method. Woven cloths having a stainless steel fiber interlocked with the cloth fibers as shown in FIGS. 2-4 were cut into square meters. The woven stainless steel cloths were sprayed with an antimicrobial binder formulation having the composition and concentration outlined in table 1. Primal™ NW-1845K Binder is a non-crosslinkable styrene acrylic binder including α-Methylstyrene and N-butylmethacrylate. RHOPLEX™ TR-407 Emulsion is a crosslinkable acrylic emulsion in water including Methyl methacrylate. The ZPT used was Kopthione—dry powder from Kumar organic products limited.

The sprayed steel cloths were then cured at 110° C. for 15 minutes. Polyurethane foam sponges with a density of 20-25 kg/m3 were cut into rectangles having the same dimensions as the stainless steel cloths. The cloth and foam rectangles were clipped together and then adhered to each other using water based polyurethane glue PL101 and pressed through two roll coaters to produce foam cloth scrubbers. The scrubbers were then allowed to rest at room temperature for 24 hours, producing samples S1-S4. A comparative sample, CS1, having no antimicrobial binder was produced.

Stiffness Testing

Samples S1-S4 and CS1 had their stiffness measured using a Gurley Bending resistance tester model No. 4171. Each sample was cut into 5 scrubbers measuring 1.5 inches by 4.5 inches. Stiffness measurements were taken with the Gurley Bending resistance tester using a dead weight of 200 gms and the dead weight in position 4 and the average stiffness of the 5 scrubbers of each sample was calculated. The resulting stiffness measurements can be found in table 2 below.

TABLE 2 Stiffness Sample Stiffness (mg) CS1 1250-1800 S1 1900-2200 S2 2100-2900 S3 2800-4700 S4 3250-3750

As can be seen, stiffness increases with binder concentration up to 150 GSM. However, the scrubbers with concentrations above 100 had sharp edges resulting in an uncomfortable hand feel. Sample CS4 had too soft of a hand feel while sample CS5 was too hard.

Scrubbing Effectiveness and Longevity

Sample S1-S4, an EXO steel scrubber (sample CS2), and a scotchbrite nonwoven scrubber (sample CS3) had their scrubbing effectiveness and longevity tested according to the following method. Stainless steel plates were buffed with a nonwoven plate. A mixture was prepared according to the composition detailed below in table 3.

TABLE 3 Food Composition Wheat flour 3.3 g Whole Gram Flour 3.3 g Rice Atta 3.4 g Sunflower Oil   5 g Water 10 ml

25 g of the mixture was added to the stainless steel plate and spread into a 7-8″ diameter. The stainless steel plate with the food mixture was placed on a 200° hot plate and the food was charred for 2 minutes. The charred food was then allowed to cool at room temperature. An exo dish wash soap bar was grated, and the grated soap was mixed with water in a 1:1 wt ratio. 5 ml of the soap solution was dispensed onto the charred food plate. The plate was scrubbed using a sample scrubber 6 times in the clockwise direction and 6 times in the counterclockwise direction. The time spent scrubbing was recorded. After scrubbing 6 times in each direction, the timer was stopped, and the plate was rinsed with flowing water. The scrubbing, timing, and rinsing steps were repeated until the charred food was completely removed. The process was repeated multiple times daily with the total scrubbing time being recorded. Specifically, for sample S2, the process was done 30 times per day for 8 days, for a total of 240 plates. For sample CS2, the process was repeated 27 times per day for 5 days for a total of 135 plates. For sample CS3, the process was repeated 28 times per day for 5 days for a total of 140 plates. For Samples S1 and S3, the process was repeated 25 times per day for 4 days and a total of 100 plates. For sample S4, the process was repeated 25 times for one day only. Average daily scrubbing times can be seen below in Table 4. Further, FIG. 7 includes images of samples S1-S3, CS2, and CS3 after each day of use.

The samples were tested for antimicrobial activity according to ASTM 2149-13a (1 g sample; 4 hrs.). The samples were tested against Staphylococcus aureus (ATCC 6538); Escherichia coli (ATCC 25922) and Klebsiella pneumonia (ATCC 4352). Results can be found below.

Peel Strength Testing

Samples PS1-9 and PW1-5 were prepared according to the table below with the same process described above for other samples with the following differences. Samples were cut into rectangles of 38 mm*190 mm. The woven steel was only adhered to the polyurethane foam along half of its length (95 mm out of 190 mm). The other half of the steel and foam were not laminated for peel strength testing. The ZPT used was Kopthione—dry powder from Kumar organic products limited. For samples PS1-9, a solvent based polyurethane glue was used (PL101).

The samples underwent peel strength testing according to the following process. The not laminated end of the woven steel and foam backing were clamped to the jaws of a peel strength testing machine from international equipment (year 2008; SR. No. 340). The bottom jaw of the machine was clamped to the foam backing. The bottom jaw pulls down at a constant rate of extension and the force is recorded as the peel strength. Peel strength testing was repeated 5 times for each type of sample. Peel strength measurements were taken in the cross direction and not machine direction.

Samples also went soap delamination testing. 50 g of EXO dishwash soap bar was mixed with 4 L of water. Samples were fully submerged for 24 hours. After 24 hrs., samples were removed and delaminated by hand. Samples that delaminated at the interface instead of tearing the backing were noted as delamination failure. Results for peel strength and soap delamination testing can be found below.

TABLE 8 Peel testing Average Peel Soap Sample Strength (kg) Delamination test PS1 0.85 Fail PS2 1.01 Pass PS3 1.23 Pass PS4 1.2 Pass PS5 1.36 Pass PS6 1.36 Pass PS7 1.8 Pass PS8 0.91 PS9 0.85 PW1 0.42 PW2 0.85 PW3 2.08 PW4 2.42 PW5 3.48

Samples PW1, PW2, and PS1 delaminated at the sponge/woven interface during peel strength testing. Other samples tore within the sponge layer. Sample PW7 had undesirably high peel strength due to the large amount of glue. Additional testing is being performed on peel strength at various ZPT concentrations for various types of ZPT according to the table below.
